The Hidden Life Of the Cell (57:24)
There is a battle playing out inside your body right now. It started billions of years ago and it is still being fought in every one of us every minute of every day. It is the story of a viral infection - the battle for the cell. This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal. Exploring the very latest ideas about the evolution of life on earth and the bio-chemical processes at the heart of every one of us, and revealing a world smaller than it is possible to comprehend, in a story large enough to fill the biggest imaginations.
You may be familiar with molecular movies from my two previous megaposts collecting them, but this extended documentary uses original animation that is collected into a coherent educational narrative and is just so fucking gorgeous. Enjoy. [more inside]

Five years ago this week, the BBC started broadcasting one of the most extraordinary documentaries ever to grace television: Planet Earth
. The culmination of five years of field work
, it employed the most cutting-edge of techniques
in order to capture life in all its forms, from sweeping spaceborne vistas to shockingly intimate close-ups
-- including many sights
rarely glimpsed by human eyes. Visually spectacular
, it showcased footage shot in 204 locations in 62 countries
, thoroughly documenting every biome from the snowy peaks of the Himalayas to the lifegiving waters of the Okavango Delta
, a rich narrative tapestry backed by a stirring orchestral score
from the BBC Concert Orchestra. Unfortunately, the series underwent some editorial changes
for rebroadcast overseas. But now fans outside the UK can rejoice -- all eleven chapters of this epic story are available on YouTube in their original form: uncut, in glorious 1080p HD, and with the original narration by renowned naturalist Sir David Attenborough
. Click inside for the full listing (and kiss the rest of your week goodbye). [more inside]

Horizon asks "What is reality?"
-- youtube for links for those outside the UK: 1
. It's a hard question. To help you answer it, Stanford has a set of free courses available on line by Leonard Susskind:
, New Revolutions in Particle Physics
, Quantum Entanglement
, Special Relativity
, Classical Mechanics
, Statistical Mechanics
, The Standard Model
. (Each link is to lecture 1 of a full college course of a dozen or so lectures.) If you need help with the math, the Khan Academy
should help get you up to speed.

Reith Lecture 2005: The Triumph of Technology
Lord Broers -In the five lectures, he sets out his belief that technology can and should hold the key to the future. He says: "It is time to wake up to this fact. Applied science is rivalling pure science both in importance and in intellectual interest. We cannot leave technology to the technologists; we must all embrace it.

a Smithsonian exhibit about a 1999 expedition. 'Whether living or extinct, on land or at sea, in literature or in life, large animals have long fascinated people. The largest animals have been known and hunted since prehistory: whales, walruses, elephants, rhinos, hippos, giraffes, and large fishes... However, one large animal has gone almost unnoticed or certainly unobserved in its habitat. That animal is the giant squid. Although these animals have been found in the nets of commercial fishermen, in the stomachs of sperm whales, and washed ashore on different continents, no scientific information has been gathered by direct observations of live giant squid ...
